Figure 1: An optical microscopy image of the pressure sensor fabricated using the contact lift-off mesa-transfer process. The gold parallelogram is the pressure sensor. About 1024 circular cavities are covered by this parallelogram gold membrane, which is 140 nm thick. The underlying PDMS on ITO-Glass is patterned with 25-µm- diameter circular cavities with about 5-µm to 7-µm spacing between the circles.
